Setup, Compatibility & Care
To install this cylinder, you must first remove the existing cylinder by unscrewing the retaining screw on the door edge and rotating the key to align the cam. Ensure you measure your door's thickness accurately before installation to select the correct size, as an improper fit can compromise security.
For maintenance, avoid using harsh chemicals or oils on the cylinder mechanism. Because the internal parts are rustproof, an occasional wipe with a dry cloth is usually sufficient. If the key feels stiff, use a specialized graphite-based lock lubricant rather than liquid oils.
